Abstract

The preparation of pent-2-en-4-ynylamine and pent-2-en-4-ynylthiol and their derivatives from 5-bromopent-3-en-1-yne was studied. Moreover, in connection with the preparation of the bromide, the rearrangement-bromination of vinylethynylcarbinol was found to give three isomeric bromides, 5-bromopent-trans-3-en-1-yne, 5-bromopent-cis-3-en-1-yne, and 3- bromopent-1-en-4-yne. Pent-2-en-4-ynylamine was obtained from 5-bromopent-3-en-1- ...
